|D. Wireless network switch
||Turn the optional IEEE 802.11 wireless network radio and optional Bluetooth radio on or off.
Note: The wireless network switch turns on both the optional wireless LAN and optional Bluetooth. The switch must be turned on for the wireless LAN and Bluetooth function keys to work (Fn+F2 for wireless and Fn+F6 for Bluetooth). If you have turned on the wireless network switch and then used a function key to disable one of the functions, the option selected remains until the wireless network switch is turned on and the function key is once again used to change the setting. For example; if you have turned on the wireless network switch to enable the wireless LAN and Bluetooth, and then used the Fn+F6 function to disable the just the Bluetooth option, even after turning the wireless switch off and then back on, the Fn+F6 function key must be used to enable the Bluetooth option again.
